I have a solid state drive, 8-core processor, and a nvidia 970 geforce graphics card. I can play skyrim on custom extra high modded graphics, yet I have trouble running this game. Why? Also after I completing a mission I will than experience lag spikes or fps shutters. I'll quit the game validate it through steam and I always get the same 10 files won't validate, and it only shows up after I start up the game after it patches.

Anyone care to explain why i get this.

I have the latest updates for everything and I keep my computer clean.
